Application filed January 9.1904. Serial No. 188,300-

Patented oetf'l'i, 1905 To all whoni, it mty concern: v

Be it known that LJAMEs A. H nn1uoa,a citizen of the United States. residing at lhiladeh -'phia, in the county of Philadelphia and State of Pennsylvania, have invented certain improvements in Furnaces, of which the following is a specification.

This inventionrelates more particularly to 'furnacesof the regenerative type; and it has as its primary ob ects to provide an unproved construction'having means for taking care of the slag that overflows at the ports,

sectional view taken on the line 2 2 of Fig. 1.

Fig. 3 represents a vertical sectional view taken on the line 3 3 of Fig. 1, and F ig.;l represents-a horizontal section taken .on the 'line {L 4 of Fig. 1;

As shown in the drawings, the heatingehamber "1 has the superposed ports 2 and b communicating therewith, which are connected bythe, respective lines 4 and 5 with the ports. 6 and 7, communicating with the regenerators 8 and 9, the fines 5, cminnunicating with the chambers 12 and 12;. between the regenerator-wallslO and 11 and the regenerators 8 and 9. The chambers 12 and 13 are provided, respectively, with the sand bottoms l 14 and 15, extending downwardly and outwardly to the doors or manholes i6 and 17' of the closures 18 and 19 therefor. @The chain-- bers and passages thus formed, divided by the walls 10, 11, and 20, have their outer i walls 21 and the connecting-arches 2:2 and 2;"

bound together with the interior walls by the e trusses 23 and the tie-rods 24-. The heartlr' is carried by the I-hars 26. resting upon the longitudinal girders 27, which are carried by the walls of the regrnerators 9; These girders have their ends engaged by the shoes which, with the I-hars,carr,y the chill-frames 29. above 'the regencrator-chambers 9, the

wall 11 of the fine 5 being supported hy the shoe and frame.

it will now be understood that slagor other matter overflowing from the furnace-chamher 1 through the ports 3 will deseend'through the lines 5 to the slag-chambers l4 and 15, whose outwardly-inclined. bottoms render it readily removable through the doors 16 and 17 or through the closures l8 and 19.

The gas-ports at each end of the furnace are provided with separate passages-to separate slag-chambers. and each of these passages has a separate port communicating with a regencrator. As the passages at each end of the furnace cmnmunirate with different parts of the rcgcnerators in passing therethrough the waste gases to the stack and the gas for combustion to the furnace-chamber, a better distribution of the gases is obtained. both in heating the checkers and in heating the incoming gases, for the separate iiues connected with the regenerators at different points thereof avoid the concentration of the gases in a single current which does not reach theextremities of the regenerator. In like manner the air-ports at each end of the'furnaee are provided with separate passages,eonnected by separate ports with dill'erent parts of the i'egenerator. so that the outgoing waste gases. I

and the incoming air are better distributed and a better heating eflectobtained.

l-laving described my invention, 1 claiin -f 1. A furnace having a heating-chamber, a plurality of regenrrators-at each end of said .heatirig-chamber, a pluralitwof gas-passages taninectiug each end of said heating-chamber with dillerent parts of a regenerator therefor, a separate slag-pocket connected with each of said passages and separated from the connec- Lions thereof with the regenerator therefor,

and a plurality of airpassages connecting each end of said licatiug-chzunber with dili'erent parts of a regenerator therefor, substantially as specified. I I

2. A furnace having a heating-chamber, a plurality of regenerators at each end thereof extending transverse]; thereto, a plurality of separate passages connected with each end of said heatirig-chamber and extending downwardly between the regenerators therefor, a slagpocket at the bottom of each of said passages, and separate ports connecting one of said regenerators with said passages above said slag-pockets, said heating-chamber being supported at ins respec tive ends by walls of but one of the regenerators connected there- 5 with.

In testimony whereof I have hereunto set my hand, this 26th day of December, A. D.
